Application mea peember 23, 1907. serial No. 407,695.

To all 'whom it may concer-1t:

` Be it known that I,- ONESIME E. MICHAUD, a citizen of the United States, and a resident of the city of St. Louis and State of Missouri,

5 have invented anew and useful Im rovev ment in Ball-Bearings, of which the 'ollow- .ing is a speciiication. This invention -relates to antifriction "bearings and more articularly t0 ball-bearings for vehicle whee s.

It has for' its principal objects to provide for the application of antifriction bearings to ordinary vehicle'wheel hubs with only slight alteration of the hub or axle spindle; to sim- 15 phfy the construction and to minimize the number of adjustments of the parts of such bearings; to provide for the removal of the axle spindle Without disturbing the bearings;

to avoid dragging and to secure a true rolling movement of the balls in their bearin s; and to attain certain. other advantages iereinafter more fully set forth. I

The invention consistsin the arts and in the arrangements and combinations of parts hereinafter described and claimed.

In the accompanying drawings, which form part 0f this speciiication and wherein like symbols refer to like parts wherever they occur, Figure 1 is a longitudinal section of a `wheel hub showing one form of my invention ap lied thereto; Fig. 2 is a side View of a spin le-sleeve and., ball-bearings detached from the hub; Figs. 3 and 4 are end views thereof; -Fig: 5 is a side view of one of the ball-bearings detached from the spindle- 'sleeve; Fig. 6 is an end view of the opposite ball-bearing; Fig. 7 is a side view of the opposits ball-bearing with its ball-retaining lock detached; Fig. 8 is a section on the line 8-8 of Fig. 7; Fi 9 is a longitudinal section of the spindle-gie the hub; Fig. 10 isa longitudinal section of a wheel hub showing a modification of my invention; Fig. 11-is an end view of one *ofy the ball-bearings of Fig. 10 detached from the s indlesleeve;'Fig. 12'is a side view thereof;

ig. 13 is an end view of thevopposite ball-v bearing; Fig. 14 is a section thereof on the line 14-14 of Fi l 15;`and Fig. 15 is an end view of the same iearing with itsball-retainin block detached.

eferring more' particularly to Figs. 1 to 9, inclusive, the hub of the wheel preferably comprises an outer metallic'shell or casing(` with the hub of the wheel.

eve detached from l wheel spolres 3. The end ortions 4.0i the casing 1 are circular. Pre erably,ithe interior faces of said circular end portions are ta- ;pered slightly as at 5, so as to provide outwardly ilaringcircular lpockets or'seats for counterpart end portions 6 of a spindle sleeve or axle box 7. Thisspindle-sleeve is made in two separable sections. Preferably, the sleeve portion of one of said sections iselongated and it is provided with external screw threads 8 at its end which are adapted to iit internal threads 9 in the short sleeve portion of the other section- -lBy this arrangement,

the spindle sleeve 6-m`ay be easilysecuredin the hub by inserting the sleeve sections 1nwardly from the res ective vends 'of the hub and screwing said s eeve sectionstogether until their tapered portions 6 are .drawn tightly into the flaring seats 5 provided there- 1 in with a wooden or othersuitable ii ler 10.

The spindle-sleeve 7 is rovided at'each end with internal screw-t eaded sockets 11.

These sockets are adapted to receive the rel spective antifriction bearings.

In the construction illustrated in'Figs. 1 to 9, inclusive, the antifriction bearing at the inner end of the hub com rises an externally threaded outer bearing rmg 12 which 1s rovided with an annular shoulder 13. his

bearing ring is adaptedto be screwed tightly into the threaded' socket 11 soasl to rotate rin -14 is referably provided on its outer cylin rical ace with two grooves or raceways which are arranged-to'coperate with annular raceways formed on the interior cylindrical face of the outer' bearing rin 12. In the raceways thus formed are antifnction balls 15.

The antifriction bearing at the outer end of the hub is somewhat simlar'to the one just described. It comprises an outer bearin rin 16 lwhich is externally'screw-threade an provided with an annular shoulder 17 Its coperating inner bearing ri'n 18 is provided with an inwardly disposed an ed 0rerably provided with two annu ar raceways p for balls 22. The-end faces of-the respective bearing` rings- 12 and 16 are provided with holes 23 `lor other suitable, means for the ,atf

tachment of a Spanner or wrench. g The outer 9o Aninner bearing antifriction healing is provided withl a washer' o1" acking rin 24. This packin j ring yis -pre erably fitte in-an`annular periperal depression 1n the end lofthe bearing ring-Sand 1t is "held in place by an inwardly posed annular shou inner bearing. t is v tted in correlated annular depressions 27 and 28 in the end faces of bearing' 12 and 14, respectively.

` This packm ring 26is held in place b a collar or shoul er 29 on the axle 30. T e axle lshown isfprovided with Va slightly ta ered spindle 31; spindle has a reduce end portion 32 which is screw-threaded, as at 33,

to receive aA securing nut 34. Preferably, this nut is'circular in cross section and its en d -is closed, as shown. A'hole or notch 35 1s provided in the nut for the engagement of a special Spanner or Wrench. Obviously, however, the nut y34. may be of any other desirable form.

In order to minimize the number-vof parts and avoid numerous adjustments thereof, as

well as to facilitate the lacing of the balls Ainthe bearings, the outerA carin rings 12 and 416 are slotted lengthwise as s own atv 36 1n Figs. 7 and 8. These slots 36 are ofa sufficient width to Ipermit the free assage of the bearing ballst erethrough. refera'bly, the slots are slightly ta ered or flared-outwardly. Segmental wedge-s aped ller or ball retaining blocks 37 are provided to iit said slots,

-and the outerfaces of said ller blocks are rings 12 and 16 are screwed into place in the spindle-sleeve, the filler blocks 37 are /held' securely in lace with their respective bearing rings. hus, when the bearin s are assembled and placed in the spindleeeve the outer rings and filler blocks are as one integral piece. This construction and arrangement greatly reduces the number ,of parts. Hence the number of adjustments is lessened and the bearing is made more stable. The bearings thus arranged vare readily interchangeable and the arrangement ofthe race- Ways is such that the .balls have a true rolling movement.

By providing two raceways for each bearing, as shown, the balls and their bearings are not subjected to a rocking motion. Therefore, the bearings ,may be used for a 65 long time, because undue wear is avoided.

der 25 on the bea-ring ring 16. A similar packin rin 26 isv provided for the and shoulder formed by Furthermore, in case a bearing should become damaged it may be readily replaced.

Bearings constructed and arran ed according to my invention may be casi y adapted uf) ordirlila Wheel hubs `by a slight alteration o -suc the spindle sleeve7, and possibly insert metal rings or bushings in the ends of the hub to provide seats equivalent to the circular portions ,4 and tapered seats 5 shown in thedrawings. It is also obvious that hubs equip ed with the bearirjizg's" may be readil app ied to ordinary a e spindles with 'ttle or no alteration whatever.

1As. shown in Fig.4 v1, the shouldered end portion 32 of the spindle 31 is fitted into the pocket 20 of the inner bearing'ring 18, and lt'is clam ed tightly thereto b the nut 34.. Obvious y, it is only essentia that the distance between the collar or shoulder 29 the reduced end portion 32 of the spindle 31, Should be sufticient to prevent binding and to permit ofthe proper alinement of the ball raceways when the nut 34 is jammed against the ring 18. Incase the spindle is too short, it is only necessary to inte ose a washer or liner Abetween the shou dered end of the spindle and the seat of the pocket 20. So, too, if the spindle is too long, a-washer or liner may be placed between thecollar or shoulder 29 and bearin ring 14.

In the modiication lustrated in Figs. 10

to 15, inclusive, the general arrangement is similar to that hereinbefore set forth. c .In

this case, the inner bea-ring ring14. is, preferably provided-with an annularshoulderA 41 and it 1s hollowed to receive the collar 29t on the 'axle 30'. The spindle 31* is provided With a screw-threaded portion 42 which is adapted to'bescrewdtightly into an interiorly screw-threadedportionof the bearing ring 14". The end ofthe spindle 31 a is preferably reduced asat 43 so as to fit into the pocket 20a of the inner bearing ring 18.

The outer end of this ring is closed, as is' also the outer end of the outer bearing ring 16a. To conveniently attach or detach the Vinner bearing, the ring 14 is provided with a hole 44 through its shoulder 41' and arranged so as to register with one of the holes 23 in the bearing ring 12, in order that a projection on a wrench may be inserted into said hole 23. In other respects the construction and arran emcnts are identicalf-L to be limited to the exact constructions andarrangements shown. l
